Heavy rains in northwestern Arkansas are beginning to cause flooding downstream in northeastern Arkansas. The White River, a tributary of the Mississippi River, appeared flooded in this Moderate Resolution Imaging Spectroradiometer (MODIS) image, acquired by the Aqua satellite on April 27, 2004. Blue patches of water line the river, which is barely visible in an image acquired just ten days earlier. On the right side of the image, the Mississippi River forms Arkansas’ eastern border with Tennessee. A narrow strip of Missouri is visible along the top of the images. Vegetation colors the false color images bright green. Clouds appear light blue. Source: Jacques Descloitres, MODIS Rapid Response Team, NASA/GSFC
